Thermal Infrared Hyperspectral Camera can be applied similarly to a Thermographic camera, with the fundamental difference that each pixel contains a full LWIR spectrum.

Consequently, the object identification can be performed based on both the temperature and surface material. Such chemical identification of the object can be performed without a need for an external light source such as the Sun or the Moon. In comparison to traditional Thermographic camera, the AISA OWL image is highly detailed, yet containing the valuable spectral information.

The image above demonstrates Specim Aisa OWL chemical imaging capabilities. The emission measurement, an outdoor scan in winter conditions, ambient temperature -10 C. The contrast level indicates the temperature of the object, a temperature difference of 0,3 C can be measured. Relative radiance and absorbance spectra from a gas burst are shown with arrows. As the infrared spectra of the different substances have clearly distinctive characteristics, the detection of gas leakage and component definition is easy.
